Our "Digital Temperature Indicator," or DTI, is an irreversible temperature indicator label that allows temperature-tracking at the item level and displays the status in both visual and digital formats when an item is exposed to temperatures above a specific threshold.

 

The DTI's core technology is based on patented thermoresponsive materials. The DTI is created to broaden the usage of passive RFID/NFC labels from just tracking items to include sensing and ensuring the quality of temperature-sensitive products at the item level. The DTI is compatible with the existing RFID/NFC interrogators, software, and infrastructure. The benefits of the two technologies, passive RFID/NFC labels and time-temperature indicators, are combined in the DTI.

 

The novelty of the DTI is the ability to constantly track the ambient temperature of an attached item without any external power sources – no need for batteries or persistent RF interrogation. The DTI can expand the usability of passive RFID/NFC labels beyond the conventional item tracking.

 

The indicated status can be visually inspected by operators/users and digitally read through an RFID/NFC interrogator. The DTI is designed to be fully compatible with the existing RFID/NFC infrastructure/applications with minimal modifications. Further, the cost of a DTI is comparable to traditional RFID/NFC labels with similar dimensions and usage.
